+

+Once you've done that, your config section should look like:
+
+``` json
+{
+  "type": "mongodb",

+You can also just set the environment variable for `DATABASE_URL` to your database connection url.

+Unlike with postgres you do NOT have to create the table in your mongo database prior to running.
+
+You can also set an `expire` option to the number of seconds to expire keys in.
+This is off by default, but will constantly kick back expirations on each view or post.

+
+To use the Google Datastore storage system, you must install the `@google-cloud/datastore` package via npm
+
+`npm install @google-cloud/datastore`
+
+Once you've done that, your config section should look like this:

+
+Authentication is handled automatically by [Google Cloud service account credentials](https://cloud.google.com/docs/authentication/getting-started), by providing authentication details to the GOOGLE_APPLICATION_CREDENTIALS environmental variable.
+
+### Amazon S3
+
+To use [Amazon S3](https://aws.amazon.com/s3/) as a storage system, you must
+install the `aws-sdk` package via npm:
+
+`npm install aws-sdk`
+
+Once you've done that, your config section should look like this:
+
+```json
+{
+  "type": "amazon-s3",
+  "bucket": "your-bucket-name",
+  "region": "us-east-1"

+
+Authentication is handled automatically by the client. Check
+[Amazon's documentation](https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-credentials-node.html)
+for more information. You will need to grant your role these permissions to

+## Docker
+
+### Build image
+
+```bash
+docker build --tag haste-server .
+```
+
+### Run container
+
+For this example we will run haste-server, and connect it to a redis server
+
+```bash
+docker run --name haste-server-container --env STORAGE_TYPE=redis --env STORAGE_HOST=redis-server --env STORAGE_PORT=6379 haste-server
+```
+
+### Use docker-compose example
+
+There is an example `docker-compose.yml` which runs haste-server together with memcached
+
+```bash
+docker-compose up
+```
+
+### Configuration
+
+The docker image is configured using environmental variables as you can see in the example above.
+
+Here is a list of all the environment variables
